Answer:
In C++:
#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int main(){
string lname, fname,stringnum; int num; string login, pwd;
cout<<"Last Name: "; cin>>lname;
cout<<"First Name: "; cin>>fname;
cout<<"Four-digit integer: "; cin>>num;
stringnum = to_string(num).substr(0,4);
stringstream geek(stringnum); geek>>num;
num = num%100;
pwd = to_string(num);
if(lname.length()<5){ login = lname+fname.substr(0,1); }
else{ login = lname.substr(0,5)+fname.substr(0,1); }
cout<<"Login Name: "<<login<<endl;
cout<<"Password: "<<pwd<<endl;
return 0;
}
Explanation:
This declares all necessary variables
string lname, fname,stringnum; int num; string login, pwd;
This prompts the user for last name
cout<<"Last Name: "; cin>>lname;
This prompts the user for first name
cout<<"First Name: "; cin>>fname;
This prompts the user for a four digit integer
cout<<"Four-digit integer: "; cin>>num;
This converts the input number to string and gets only the first four integer
stringnum = to_string(num).substr(0,4);
This converts the string back to an integer
stringstream geek(stringnum); geek>>num;
This gets the last two of the four digit integer
num = num%100;
This gets the password of the user
pwd = to_string(num);
This gets the login name of the user.
This is executed if the length of the first name is less than 5
<em> if(lname.length()<5){ login = lname+fname.substr(0,1); }</em>
This is executed if otherwise
<em> else{ login = lname.substr(0,5)+fname.substr(0,1); }</em>
This prints the login name
cout<<"Login Name: "<<login<<endl;
This prints the password
cout<<"Password: "<<pwd<<endl;
